From the Service Procedure Guide I see, Reset and hold is a special state during which power is maintained to the SP assembly so that I/O modules, embedded modules, and 4-port cards can be safely removed. This state has fewer management capabilities than Service Mode, but allows for easier I/O module, embedded module and 4-port card replacement.

So wanted to know if the SP is already in 'Reset and Hold' mode, is it safe to remove the SP from the DPE. This is assuming it's not possible to get into 'Service' mode.
